ATTORNZY ratus and more draught liquid 1 for packaged beverages which Patented Feb. 15, 1944 pmlrso s REFRIGERATION APE'AMTEJS E 0. Tanner, westinfiggtuse P y, Pennsylvania Application December 2, 1941, Serial No. 8 Claims. (Ci. 62-441) This invention relates to refrigeration appaespeoiaily to a draught liquid cooling attachment for a cooler for packaged beverages.

One object of the invention is to provide a cooling attachment for a standard cooler for packaged beverages which requires but a minimum of change in the standard cooler whe i being attached thereto.

-A further object of the invention is to provide a draught liquid cooling attachment for a. cooler stantially decreases neither the storage space oi the cooler nor obstructs its access openin These and other objects I oi -this application, in which Fig. 3 is a section showing somewhat schematically the spout and valve or the draught liquid cooling attachment;

Fig. d is an enlarged section on the lineH -IV of Fig. 1; I

Fig. 5 is a plan view of the draught'liouid cooling unit or this invention; and,

Fig. 8 is an enlarged section on the line t -V of Fig. 1..

Referring now to the drawings for a detailed description oi the invention, the standard cooler for packaged beverages will first be described. The reference numeral it! represents aninsu lated cabinet embodying a chamber ii adapted to contain a cooling bath i2 such as water. The entire top of the insulated cabinet it is open it rests.

unit it communicates with a pipe The pipe M then travels downwardly along the wall of the chamber H to adjacent the bottom thereof and then horlzontallyealong the bottom of the chamber ii in a plurality of convolutions 36. The pipe it thereupon travels upwardly adjacent the downwardly running portion thereot and emerges from the cabinet it it is preferably surrounded with heat insulation (not shown).

The portion to voluted along the bottom of the chamber ll provides a reservoir for the cooled draught water and likewise provides large heat transfer surconnection between the two The cooling coils is are secured to a smcer it which normalw rests on the bottom of the chamber it when the water cooling unit of this invention is not attached to the beverage cooler but rests on the convoluted portion 36 of the pipe M when the water cooling unit is in place.

It will be obvious from the above that the the insulated cabinet at. a

of the pipe it which has conwater cooling unit of this invention may be secured readily to a standard cooler for bottled beverages of the type described. All that is required for such installation is to drill holes for the self-tapping screws 23 and to cut a notch 30 in the rubber sealing gasket Hi for the pipe 34. The cooling coil l5 of the cooler is then bent upwardly, the convoluted portion of the pipe 34 is slipped underneath the cooling coil t6, and the end hooks of the convoluted portion hooked to the cooling coil it. The cpoling unit of this invention is then connected to the water mains and to a waste pipe leading to a sewer and is ready for use. The water cooling unit does not obstruct the access opening of the cooling chamber and does not substantiallydecrease its storage space for packaged beverages.

While I have shown by invention in but one, form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit theerof, and I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.
